Abstract
amorphous ferromagnets were prepared that show a magnetoresistance anisotropy (AMR) reaching 26% at 10 K, in a 50 kOe field. This is a striking result, since the AMR of typical amorphous ferromagnets does not exceed 1%. Large excess resistivity caused by domain walls is found to scale with β, where β’ is the tangent of the Hall angle.
